Given what you've written, I guess I have a few questions. I think the idea of an internship (or maybe apprenticeship) sounds about right, but obviously there has to be a "fit".

1) What was your area of expertise before the amnesia?

2) What do you want to do when you've recovered your abilities? (this might be a good time to switch if you've had your eye on something).

3) Where are you?

4) Would you be comfortable working with a (small) team of people?

5) Would you be comfortable being the subject of research?

I don't want to make any representations for my employer (a major university), but after almost 30 years in industry, I've been amazed at both the positive and negative difference between a university and a company. I think a university environment would be a good fit for you. One of the positives I've seen is an amazing willingness to adapt to a person's needs. There are all sorts of classes close at hand (and you can audit them for free), and I think you could probably find a "champion" in someone who is interested in the process of rehabilitating those with your condition.

I imagine that most other major universities would be a similar environment. Ours even has an office that helps students, staff and faculty adapt to their disabilities (or adapts the workplace as needed). If you want to stay in your current area, try the university that's local to you. If you're interested in moving for the right opportunity, I can try to find someone at work to see if something can be arranged. I'm sure there are 30 others here at HN that can do the same at other universities.
